HEADLIGHT.

Application filed January 6, 1922. Serial No. 527,415.

T 0 all whom it may concern:

Be it known that I, Mosns J. DAVIS, a citizen of the United States,residing at Pueblo, in the county of Pueblo and State of Colorado, haveinvented a new and useful Headlight, of which the following isspecification. i

This invention relates to headlights primarily designed for use onloconiotiVes'although the improvement constituting this invention canalso be embodied in connection with automobile headlights, etc.

It is an object of the invention to provide a headlight which can bequickly changed so as to throw either a white or a colored light(preferably red).

A further object is to provide a structure in the form of an attachmentwhich can be applied readily to headlights already in use and by meansof which the light can be changed from white to a color such as red.

An object of the present invention is to provide a means whereby in anemergency the light projected from the headlight can be changed to redso as to serve as a danger signal.

.Another object is to provide a structure of this character which issimple, durable and compact and can be easily operated.

VVith' the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that, within the scope ofwhat is claimed, changes in the precise embodiment of the inventionshown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings Figure 1 is a front elevation of a headlight having thepresent improvements combined therewith, parts being broken away.

Figure 2 is a side elevation thereof, parts being shown in section.

Figure 3 is a section through a portion of the device.

Figure 4 is a rear elevation of the attachment, a portion being brokenaway.

Referring to the figures by characters of reference 1 designates acylindrical headlight housing of the usual or any preferredconstruction, the same being provided with a transparent lens 2 forthrowing a white light;

The attachment constituting the present invention includes a rear crossbar 3 and a front cross bar 4-,these bars being attached to the frontand back of the headlight housing and being secured at their ends toside rails 5 the forward ends of which are downturned as indicated at 6so as to extend to opposite sides of the lens 2. Formed Wltlll-fl theinn-er sides of the rails 5 are longitudinal channels 7, these channelsextending down wardly within the downturned portion 6 as shown in Figure3. A cover plate 8 is secured on the rails and covers the spacetherebetween, this plate being provided with a central raised portion 9extending longitudinally thereof.

Mounted to travel within the channels 7 are the ends of parallel crossrods 10 and 11, these rods being secured to the rim or frame 12 of acolored lens 13. An arm 14: is extended from the rod 10 and is pivotallyconnected to an actuating rod 15 which extends rearwardly under theraisedportion 9 of the cover plate 8 and to any convenient point whereit can be reached readily for the purpose of actuating the movable lens.

Under normal conditions the rods 10 and i 11 are seated between theupper or horizontal portions of the rails 5 so that the lens 13 and itsframe 12 are thus housedbetween rods 10 and 11 to slide forwardly withinthe channels 7 and thence downwardly w'thin those portions of thechannels in the depending portions 6 of the rails. Thus the lens 13 andits frame 12 will be projected forwardly and swung downwardly so as tocover the white lens 2 and cause a colored light to be projected. Bypulling backwardly on the rod 15 the lens 13 will be brought back toposition between the hous ing 1 and the plate 8 Obviously, therefore,the color of the light projected from the headlight can be quicklychanged in an emergency.

The device described can be applied readily to headlights already in useand is not only efficient for use in connection with locomotives but canalso be used, to advantage on automobileheadlights,etc. Yhile ill) a redlens is preferably used it is to be understod that lenses of othercolors can be employed when desired.

It is to be understood that the rod 15 can be mounted within a suitableguide such as shown at 16 in Figure 4, thereby to hold the rod in properrelation at all times to the arm 14.

What is claimed is 1. The combination with the cylindrical headlighthousing of a locomotive or the like, of a one-piece supplemental lensnormally housed above and outside the housing, means for sliding thelens, and means for guiding said lens during its sliding movement, fromthe top of the housing down wardly into position across the lens of thehousing, and a cover plate extending over the housing for protecting thelens while in position above the housing.

2. The combination with a cylindrical headlight housing, of parallelguide rails supported above and upon the top of the housing and havingdownwardly extending front end port-ions, cross members slidablyengaging the rails, a one-piece lens fixedly connected to the crossmembers and normally supported thereby above the housing and between therails, and means for sliding the cross members, said rails constitutingmeans for guiding the sliding cross members to position across the upperand lower portions of the housing lens thereby to support the one-piecelens in position across the front of the housing.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
